The person is regarded as one with a criminal record from the day when an accusatory sentence came into legal force until the day of quashing or expunging the criminal record.

The criminal record is quashed:
1) In case of conditional punishment, after the expiry of the probation period after parole;
2) in relation to persons sentenced to a punishment softer than imprisonment, 1 year after having served the assigned punishment;
3) in relation to persons sentenced to imprisonment for not grave or medium-gravity crimes, 3 years after having served the assigned punishment;
4) in relation to persons sentenced to imprisonment for grave crimes, 5 years after having served the assigned punishment;
5) in relation to persons sentenced to imprisonment for particularly grave crimes, 8 years after having served the assigned punishment.

If the person has been exempted from serving the punishment on parole or the unserved part of the sentence was replaced with a softer punishment, then the quashing of the criminal record is calculated after having served the basic and supplementary punishment.
